Günther, R. T., Oxford Gardens. (280 pp. numerous illustr. 

 Oxford, Parker & Son. 1912. 6/—.) 



This book is a guide to the Oxford Botanic Garden depicting 

 with great fidelity not only the existing arrangement of the plants, 

 but aiso the history of the garden, herbarium and botanical departe- 

 ment of the University from the foundation of the Garden in 1621. 

 In a series of Appendices many College Gardens famous for their 

 trees, i.e. are dealt with, together with much other relevant matter. 

 Here will be found (p. 253—259) under the title "The Gardens of 

 the Winds or Birds" a very interesting record of the author's own 

 observations, continued for over 20 years, on the epiphytes which 

 established themselves upon the pollarded willows of "Mesopotamia". 

 In all, the epiphytic population of 114 willow trees has been under 

 Observation and their vicissitudes through this period tabulated. The 

 book abounds in interesting small talk about noble trees or their 

 planters, and as the author writes with a cultured pen, it should 

 find many readers both in and out of Oxford. F. W. Oliver.
